x in (-oo:+oo)

x^2-2 = (-7*x)/4 // - (-7*x)/4

x^2-((-7*x)/4)-2 = 0

x^2+(7/4)*x-2 = 0

x^2+7/4*x-2 = 0

DELTA = (7/4)^2-(-2*1*4)

DELTA = 177/16

DELTA > 0

x = ((177/16)^(1/2)-7/4)/(1*2) or x = (-(177/16)^(1/2)-7/4)/(1*2)

x = ((177/16)^(1/2)-7/4)/2 or x = (-((177/16)^(1/2)+7/4))/2

x in { (-((177/16)^(1/2)+7/4))/2, ((177/16)^(1/2)-7/4)/2 }
